CFLRYSOMELIDjE. 
Genus DIAPROMORPHA. 
Diapromorpha, Lacord. Mon. Phytoph. ii, 1848, p. 227 ; Chapuis, 
Gen. Coleopt. x, 1874, p. 121. 
Type, I), trifasciata , Oliv., from Africa. 
Range. Africa and India. 
Body subcylindrical, robust, often narrowed posteriorly ; the 
head deflexed, deeply inserted; eyes large ; antennae robust. Thorax 
subcylindrical, strongly convex, the posterior angles more or less 
distinct. Scutellum small, deflexed. Elytra with very distinct 
lateral lobes, only partly covering the pygidium. Legs robust, 
tibiae .widened anteriorly ; the tarsi robust, of nearly equal length, 
rather short, the first joint shorter than the following two 
united. 
These insects may be distinguished from the genus Clytra by 
their more cylindrical shape and the shape of the elytra ; the latter 
have distinct lateral lobes and not only leave the pygidium partly 
uncovered but often also the sides of the abdomen ; the pro- 
sternum is either visible in shape of a very narrow ridge or is 
entirely obsolete. 
Section I. 
Species of large size (8-12 mm.). 
282. Diapromorpha gigantea, Jac. Ann. Mus. Civ. Genova , xxxii, 
1892, p. 878. 
Bluish-black; elytra with basal margin, a transverse band near 
middle and another near apex, flavous. 
Convex, subcylindrical, narrowed posteriorly. Vertex of head 
swollen, impunctate, space in front of eyes finely rugose ; clypeus 
broad, flattened, bounded at sides by a deep oblique groove, 
preceded by a narrow ridge ; labrum and palpi black ; antennae 
scarcely extending to base of thorax, basal three joints dark fulvous, 
second and third very small, rest triangularly widened. Thorax 
about twice as broad as long, sides narrowed in front, posterior 
angles distinct, posterior margin produced in a rounded lobe at 
middle ; surface with some obsolete depressions near the sides, 
shining, almost impunctate, some extremely fine punctures onlv 
on the sides. kScutellnm triangular, smooth. Elytra closely and 
distinctly punctured, interstices very finely punctate ; black, basal 
margin narrowly flavous, this colour not extending to suture ; the 
band immediately before the middle broad and of regular shape, 
extends to either margin, the preapical band more irregular and 
narrowed towards the suture. Beneath finely pubescent. Last
